From Nov. 2 to 6, the 170th Meeting of the Acoustical Society of America was held in Jacksonville in Florida State of USA. Research assistant DAI Yuyu and ZHOU Yinqiu from Research Center for Ultrasonics and Technologies of the Institute of Acoustics, Chinese Academy of Sciences were invited to attend this meeting and make presentations.

Meetings of the Acoustical Society of America which are semiannual are organized and held by the Acoustical Society of America in order to increase and diffuse the knowledge and technology of acoustics and their practical applications.

The 170th Meeting included 48 sessions of 14 different research directions, such as acoustical oceanography, animal bioacoustics, architectural acoustics, biomedical acoustics, engineering acoustics, education acoustics, musical acoustics, noise, physical acoustics, psychological and physiological acoustics, signal processing in acoustics and so on. The meeting attracted more than 900 international acoustics specialists and engineers to attend. It was a comprehensive international event of the highest academic standards in the acoustics field.

Research assistant DAI Yuyu and ZHOU Yinqiu attended the special session of “General topics in physical acoustics II” and “General topics in physical acoustics I”, respectively.

DAI Yuyu made a presentation titled “Investigation of low-frequency broadband dipole transducer driving by PMN-PT transverse shear mode”. In his presentation, a dipole transmitter using PMN-PT transverse shear mode was proposed to enhance the radiation power in the low-frequency and increase the fatigue limit of the piezoelectric bender bar.

ZHOU Yinqiu made a presentation titled “The research on piezoelectric cylindrical oscillating transducer for dipole acoustic logging”. She introduced a novel design of a piezoelectric dipole transmitter for wireline logging.

Both presentations aroused wide interests and attentions of international research scholars.

In the Meeting of the Acoustical Society of America, researchers from worldwide share hotspots and latest research progress in the acoustics field.
